EYEGLASSES.

SPECIFICATION formingpart of Letters Patent No. 762,911, dateda une 21, 1904.

Application and october 12, 1903.

To all whom. it' nur/y concern: y

-Be it known that I, MARSHALL M. Kinn, a

citizen of the United States, residing at Petersburg, in the county of Pike and State of Indiana, have invented certain new and useful Improvements in Eyeglassesof which the follow-I ing is a specification. a This invention has relation to eyeglasses, and more particularly to the means for securing the same to the bridge of the nose when worn. i

The invention appcrtans tothe type of eye' glasses in which the lenses are connected by means of a rigid bridgel in contradistinction to the spring-bridge,.the nose-pieces being mounted so as to readily conform to the shape ofthe nose and equalize the pressure thereon, 'n said nose-pieces being Ycarried byleve'rs pivotally connected-to the frame ofthe eyeglasses and acted u-pon by springs so -as to grip the nose with suiiieient force to hold the glasses in place under ordinary conditions.

For a full description of the invention and the merits thereof and also to acquire a knowl-v edge of the details of construction of the means for effecting the result reference is to be had to thcfollowing description anddrawings hereto attached.

While the essential and characteristic fca' turcs of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of -a pair of -eyeglasses embodying the invention. Fig.' 2. is an end View of one of the lenses, showing the bridge in central section. Fig. 3 is a detail perspective view of the nose-piece, the lever carrying the nose-piece, and the part to which said lever is pivotd, the par-ts'being on a larger scale.' Fig. ,4 is a central longitudinal section of the nose-pieces, showing the end portions of the supporting-levers in full. Fig. `5 is a top view of 4the glasses, showing tle parts on a larger scale, theouter portions y or clips. Levers 3 are pivotally connected infWith the depressioni), forms a socket for re- SerialpNo. 17b,70lI (No model.)

The eyeglasses may be of -any structural type or pattern so long as the lenses 1 are con-l nected by means ofV a bridge 2 of rigid material, the bridge being attached tothe lenses 'f1 in the usual manner either by means of rims tei-mediate of their ends to the eyeglasses-near the extremities of the bridge 2 andare provided at their inner ends with balls 4 and are fashioned at their outer ends to provide lingerpieces 5 Afor convenience of operation. The inner ends of the levers are curved inward toward each other to properly position the ball 4 with reference to the nose-pieces. rlphe outer ends of the levers 3 project forward `from the plane of the lenses 1 and bridge 2 a distance to admit of'the finger-pieces 5 being con venientlygrasped when placing the glasses in position or removing themfrom the nose. Springs 7 cooperate with the levers 3 to press their inner ends toward each other, wherebyA the nose-pices Gare caused to grip the bridge of the nose to hold the'glasses in place. The springs 7 may be of any consti-notion and ar-y rangement so long as they eifect the desired result. -As shown, the springs'are'of'spiral form, one" end being engaged with the frame or p'art of the structure to which the levers 3 are pivoted and the opposite end engaging with said levels in such a manner as to exert a pressure ,thereon to force the inner ends of said levers toward each other. The nose-pieces comprise a plate 8, provided at a central point with a hemispherical depression 9, with which communicates the narrow portion of a keyhole-opening 10, a com` panion plate 1l riveted'or otherwise secured at its ends to the plate 8 and having-a companion hemispherical depression 12, which,l

v ccp-tion of the ball 4 and a grip 13, the latter. 4being of cork, rubber, or other comparatively soft material to preventinjurious and annoying pressure upon the nose when the glasses are worn. The material comprising the grip- 13 may be secured to ,the plate 8 in any manner common in articles of this nature, and, as shown, the longitui-linal edge portions of the plate 8 are bent and-incline toward'eachother to enter depressions in the edges of the part Ibo between. Upon releasing the llevers 3, the

13. as indicated most clearly in Fig. 3.4 The keyhole-opening l0 admits of the ball 4 being readily passed into the depression 9 preliminary to securing the plate 11 to the plate 8. The balland-soeket joint between-the levers 3am-l the nose-pieees 6 admits of the-latter readily conforming to the shape of the nose as well as providing for varying the-inclina-v tion of the lenses Without changing the grip ofthe nose-pieces upon thebridge of the nose.

To place the glasses in position or remove them from the nose, the Enger-pieces 5 are grasped between the thumb and finger of the hand' and are pressed together, thereby moving the nose-pieees apart adistanee to admit of the bridge ot' the nose passing readily theresprings 7 regaining themselves move the levers inward at their inner ends and canse the nose-pieces to grip opposite sides of the nose, thereby holding the eyeglasses in place. The nose-pieees are self-adjusting by reason of the universal and ball-and-soeket connection with the levers 3, and the lenses may he inclined more or less to snit the convenience of the user.

Having thus deseribed the invention, what is claimed as new is- 1. In eyeglasses, the combination of levers pivoted between their ends to the frame and having their outer ends extended to forni linger-pieces, said levers being provided at their inner ends with balls, nose-pieces eo'nposed i of companion plates, eaeh having an approxiwhich unit-- mately hemispherieal depression, edly form asoeket for reception ofthe ball at the inner end of one of the levers, and a grip fitted to the plates for direct Contact with the nose, and springs cooperating with said levers to eanse the nose-pieces to grip the bridge of the nosek when the glasses are worn, substantially as set forth.

2. In eyeglasses, the combination of levers pivoted between their ends to the frame and having outer ends extended to jferm lingerpieces. said levers being provided at their inner ends with balls, a plate fitted to the inner end of eeehklever and having a hemispherieal depresslon and a keyhole-opening, the latter having its narrow portion extended into said depression, a eompanionplate secured to the first-mentioned plate and provided with a hemispherieal depression to orrn with the depression ot the first-mentioned plate a socket for reception of the ball at the inner end ot' the lever, and springs cooperating with said levers to cause the nose-pieces to grip the bridge of the nosewhen the glasses are worn, substantially as set forth.
